Abstract:
Objective:To investigate the feasibility of cochlear implantation with contour electrode in patients with Mondini malformation and analysis of hearing rehabilitation after operation.Method:Collection of 9 cases of straight electrode cochlear implantation patients with Mondini malformation, according to the age of deafness and the condition of rehabilitation, 9 patients with curved electrode implanted were matched and grouped.Retrospectively analysis of audiology characteristics, surgical technique, postoperative NRT results and map results, and evaluating the hearing and speech rehabilitation ability by CAP and SIR scores. The test parameters and rehabilitation effect of two groups' patients were compared according to different implant electrode.Result:Eighteen cases of patients with Mondini malformation are severe sensory neural hearing loss according to preoperative hearing test, 6 cases without residual hearing. By preoperative EABR test, all patients were implanted with different types of electrode. There were 4 cases of gush in operation, 2 cases of facial spasm in straight electrode group, no complications postoperative cerebrospinal fluid leakage, no facial paralysis, no meningitis and other surgical complication after operation. Detecting NRT, the inducing rate of NRT was 77.78% in contour electrode group and 55.56% in straight electrode group; 6 month after operation, the average T value was (145.11±10.88)CL in contour electrode group and (168.44±22.45)CL in straight electrode group (P< 0.05); the average C value was (182.67±14.65)CL in contour electrode group and (213.00±19.27)CL in straight electrode group (P< 0.05). Dynamic range:(37.56±6.75)CL in contour electrode group and (44.56±18.06)CL in straight electrode group (P> 0.05). Postoperative follow-ups were performed from 6 months to 4 years, the average score of CAP was 7.28±0.62 in contour electrode group and 7.22±0.79 in straight electrode group (P> 0.05); the average score of SIR was 4.17±0.56 in contour electrode group and 4.00±0.71 in straight electrode group (P> 0.05).Conclusion:Contour electrode can be chosen for bilateral serious hearing loss patients with Mondini malformation assisted by EABR, there is no significant difference compared with straight electrode in postoperative hearing and speech rehabilitation ability. The advantages are that the stimulation quantity is small, the NRT extraction rate is high, and the complication rate is low.
